BALL BEARING 6B1124 - Caterpillar

System Operation Description:The crank cycle and the number of crank cycles are programmable. The crank cycle is the amount of time for engagement of the starting motor. The crank cycle also includes the amount of time for cooling of the starting motor between crank cycles. If the engine does not start within the number of crank cycles that are programmed, "ENGINE FAILURE TO START SHUTDOWN" will be displayed on the EMCP 3. The "ENGINE FAILURE TO START SHUTDOWN" display is to inform the operator of an over crank condition.Note: Refer to the engine Troubleshooting manual for more information on engine starting and engine cranking for your particular generator set.The code for the engine over crank is generated when the EMCP 3 determines that an engine over crank condition has occurred.Test Step 1. PERFORM THE INITIAL CHECK.
Check for active diagnostic codes on the engine ECM and the EMCP 3. If any codes are present, first correct any problems that caused the diagnostic codes.Expected Result:No other diagnostic codes or indicators are active.Results:
OK - No other diagnostic codes or indicators are active. Proceed to Test Step 2
NOT OK - Another diagnostic code is active or an indicator is active.Repair: Exit this procedure. Troubleshoot the active code or indicator. Resume normal operation and verify that the problem has been corrected.STOPTest Step 2. CHECK THE SETPOINTS.
View the set points for crank duration, crank cycle rest interval, and maximum number of crank cycles. Make a note of the set points. Refer to Testing and Adjusting, RENR7902, "Electronic Control Module (Generator Set) - Configure". Compare the set points against the default set points of the particular generator set.Expected Result:The set points are correct.Results:
OK - The set points are correct for your particular generator set. Proceed to Test Step 3 for MUI engines. Proceed to Test step 4 for EUI engines.
NOT OK - The set points are NOT correct.Repair: Correct the set points. Reset the generator
